Lightroom mobile: “Shake to Undo”

Here is what happens t me a lot on iPad:To rate pictures, I set a filter to “Neutral and selected” pictures in order to hide the pictures I reject.However, while reviewing the pictures, I very often zoom (pinch) in order to assess sharpness and I LR frequently detects this as a flag rating and rejects the picture.I then must change the filter to “reject only” and then have to guess which picture I just deleted. This can be rather difficult when assessing a lot of similar pictures for best sharpness.Therefore, it would be good to implement the so handy “shake to undo” function.Cheers!
